American theatre and television director who directed The Lights of Zetar, the third-season original Star Trek episode co-written by the puppeteer Shari Lewis.
Herb Kenwith worked as a stage director and producer before becoming a television director, and was later best known for situation comedies of the 1970s.
His single Star Trek episode is The Lights of Zetar, written by Jeremy Tarcher and Shari Lewis. The Enterprise is carrying Lieutenant Mira Romaine to the library planetoid Memory Alpha when a cloud of shimmering lights kills the staff there and begins to take possession of her. The lights are the surviving minds of the people of Zetar, and Scott, who is devoted to Romaine, helps drive them out in a pressure chamber.
The episode introduced Memory Alpha, a name later adopted by Star Trek's best-known fan encyclopaedia.
